Its not easy to photograph these guys. I'm still trying.
Its June and every June millions of these guys pass through Ambergris caye. It starts about half way through the month and goes on for weeks. Day and night they flow by.

Nice photo...I was wondering why there were so many of those yesterday while we were out fishing...there's more butterflies than birds...

all headed South.
I count about 10 every five min. by just standing in one spot. It goes on for weeks like this.

A couple of years ago there was a solid 2 days where thousands were going past every minute. It was amazing to watch.

I noticed them starting yesterday too. Absolutely magical.

A few years back I thought I was seeing things when it looked like it was snowing! LOL Amoung the thousands of yellow ones there would be a black one.
Where do they hatch (come from) and where are they going?

I saw thousands of them coming back from Gallon Jug this weekend. They were swirling around in giant "swarms". I was told that they migrate to Costa Rica somewhere, make their babies, then die.

Genes are immortal. I understand what you mean by die' but if you look at it another way the butterflys immortal genes are exchanging an old bio-flying machine for a fresh one.

Point well taken!

We remember that Harriette......it went on for at least a week or more......wish we were there to see it again.
